Biometric prompt not displayed on Android 6

Question

I am trying to use BiometricPrompt to use fingerprint sensor for authentication. My minimum supported sdk is 23 (Android M).

It works on all android version I tested except for marshmallow.

In marshmallow when I try to use authenticate method on button click it calls onAuthenticationError method from BiometricPrompt.AuthenticationCallback and it gives error code ERROR_HW_NOT_PRESENT and error messsage:

This device does not have a fingerprint sensor

even when device have fingerprint sensor and it also has one or more fingerprint added to it.

I have added permission/feature in AndroidManifest.xml.

I am using jetpack library for above this.

implementation 'androidx.biometric:biometric:1.0.0-alpha04'
